The grant budget includes $100,000 in Denali Commission grant funds administered by AEA and $25,000 in matching funds provided by the City. The work conducted under the grant was organized into two phases. Phase I was a feasibility study of the proposed hydroelectric project on Indian River, and Phase II advanced conceptual design and permitting of the project. The City contracted with Polarconsult Alaska, Inc. (Polarconsult) in April 2009 to complete the authorized work items under the grant. The Phase I Feasibility Study of the project was successfully completed in November 2009. Phase II conceptual design and permitting activities were successfully conducted in 2010 and 2011. This report summarizes the Phase II activities completed under Phase II of the grant. Phase II deliverables are included in the report appendices. 2.0 REVIEW OF PHASE I TASKS 2.1 GRANT TASK 1: GRANT AND PROJECT ADMINISTRATION The City was responsible for grant and project administration. The City's Project Manager, Mr. Art Bloom, successfully coordinated all management functions for the grant. This grant task required grant administration, project coordination, grant reporting, bookkeeping, and accounting. The deliverable required of this grant task is the quarterly reports that have been submitted to AEA. 2.2 GRANT TASK 2: PHASE I FIELD WORK A field trip was completed in June 2009 under Phase I of the project. The purpose and accomplishments of the field trip are described in the Feasibility Study Report. 2.3 GRANT TASK 3: FEASIBILITY STUDY REPORT A draft of the Indian River Hydroelectric Feasibility Study prepared by Polarconsult was issued to the City and AEA for review and comment in September 2009. The Indian River Hydroelectric Feasibility Study Final Report, incorporating comments from the City and AEA, was issued in November 2009. November 2011 -Final Report 1 City of Tenakee Springs Indian River Hydroelectric Project Feasibility, Conceptual Design, and Permitting Phase II Final Report Polarconsuk Alaska, Inc. G 3.0 PHASE II TASKS 3.1 GRANT TASK 4: CONCEPTUAL DESIGN Polarconsult completed two conceptual designs for the project. The July 29, 2011 conceptual design plans are the current plans for the project. Half-size prints of both conceptual design plans are included in Appendix A. Please use the graphical scales on these plans. A cost estimate for the July 29, 2011 conceptual design is also included in Appendix A. » The first conceptual design was issued April 11, 2011. This conceptual design proposed construction of a bench along the east side of Indian River Canyon to provide access to the powerhouse site and for siting of the penstock. Based upon field assessment of the conceptual design alignments and site conditions in April 2011, this conceptual design was judged to be problematic for technical, environmental and cost reasons. » A second conceptual design was developed and issued July 29, 2011. This conceptual design minimized benching within Indian River Canyon. Construction access to the powerhouse is provided by a steep grade suitable for tracked equipment or winch operations, and the penstock was moved to the toe of the canyon and supported on trestles. Also, the power line alignment was moved to begin at the end of the City's existing electric system at the harbor, instead of at the end of existing three phase distribution approximately X mile to the west. 3.2 GRANT TASK 5: LIDAR SURVEY OF PROJECT AREA A Light Detection and Ranging {LIDAR) survey of the project area was performed to support Phase II conceptual design and permitting activities. Aero-METRIC, Inc. was contracted to perform the LIDAR survey in March 2010, and the data acquisition was completed in late April 2010. The LIDAR deliverables were provided to Polarconsult in June 2010. The LIDAR survey deliverables include: » Two-foot contour map of the project area » Black and white visible band intensity image of the project area These deliverables were used in development of the conceptual designs for the project and were also used in environmental analysis and permitting activities. A two-contour map and an intensity map of the project area are included in Appendix B. 3.3 GRANT TASK 6: STAKEHOLDER MEETING AND PERMIT APPLICATIONS A Declaration of Intention was filed with the Federal Energy Regulatory Commission {FERC) on February 26, 2010 to determine the jurisdictional status of the project.

MEETING RECORD DATEffiME: 3/10/2010 (3:00-4:00PM) SUBJECT: Indian River Hydroelectric Project-Pre Application Stakeholders' Meeting LOCATION: 400 Willoughby Avenue, Suite 400, Juneau, Alaska ATTENDEES (COUNTER-CLOCKWISE FROM SPEAKER): Joel Groves, Polarconsult (Owner's Representative) Art Bloom, City of Tenakee Springs (Project Proponent) Carol Goularte, USDA, U.S. Forest Service (USFS) Shawn Johnson, Alaska Dept. ofFish and Game (ADFG) Carrie Bohan, Alaska Dept of Natural Resources (ADNR) Division of Coastal & Ocean Mgmt. Audrey Alstrom, Alaska Energy Authority (AEA) Dan Bussard, ADNR (Water Section) Jim Anderson, ADNR (Land Section) David Lockard, AEA Doug Ott, AEA Jim Ferguson, ADFG Jackie Timothy, ADFG Katie Eaton, ADFG INVITEES (NOT IN ATTENDANCE): Sue Walker, NOAA-NMFS Phil Mooney, ADFG Stefanie Ludwig, State Historical Preservation Office Michele Metz, Sealaska Corporation Perry Edwards, USFS The stakeholders meeting was convened at 3:00PM, followed by introductions ofthe attendees. No stakeholders were present on teleconference. Mr. Groves gave a brief overview of the project history, technical details of the proposed project, and a current understanding of the resource issues pertaining to the project and major permits required for the project. (refer to the meeting agenda and information packet). The floor was opened to attendees to ask questions or offer their insights regarding anticipated permitting processes or issues. The discussion topics are summarized below. • Ms. Goularte stated that the USFS road is currently open only to off-road vehicles, and asked what type of traffic might be expected along the USFS road to support project construction and maintenance. Mr. Groves replied that a variety of motorized heavy construction equipment may be used for project construction. Project operations would normally use lighter vehicles. Major infrequent maintenance activities would require heavier vehicles. 10031 0-MEETINGMINUTES.DOC INDIAN RIVER PRE-APPLICATION MEETING DRAFT MEETING MINUTES POLARCONSULT ALASKA, INC. Ms. Goularte replied that the USFS would work with the City to permit this type of project traffic on the road. One particular concern is a failing bridge on the road in the vicinity of the project. Mr. Groves clarified that the bridge in question was above the portion ofthe road that would be used for this project. • Mr. Ferguson asked what type of intake structure was anticipated for the project. Mr. Groves replied that the conceptual intake design called for a low weir across the creek at or above the fish ladder at falls 4. A coanda-type intake screen would be built into the spillway downstream of the weir. Mr. Groves provided a brief overview of what a coanda screen is, how it works, and why it is being considered for this project. Mr. Ferguson commented that such an intake may not have impingement issues for small fish. Mr. Groves concurred, stating that flows down the surface ofthe intake screens would tend to flush any small fish off the screen, where they would be washed down the falls as under natural conditions. • Mr. Lockard asked what type of power line was being considered for this project and why. Mr. Groves replied that the type of power line had not yet been decided, but a buried cable was under consideration. An overhead line would be the other option. Preliminary review of system reliability, repair, and maintenance costs on a life-cycle basis favors a buried cable over an overhead line. The crossing at Indian River to the powerhouse would be overhead regardless of how the remaining line is constructed. • Mr. Johnson asked if the USFS had any water rights granted for the fish ladder at barrier falls 4. Mr. Groves and Mr. Bussard were uncertain if the ladder had been issued water rights. 1 Mr. Groves clarified that the USFS had defmed the minimum flow requirements for the fish ladder, and that the city's intent is to design the hydro intake to insure the fish ladder preferentially receives the minimum necessary flows during the migratory seasons. Mr. Bloom commented that the migratory seasons tend to coincide with high flows, so low flow management should not be a particularly critical issue. Mr. Groves commented that by co-locating the hydro intake with the existing fish ladder headworks at the top of the falls, the hydro project may be able to increase flows into the ladder during low flow periods on Indian River by directing in-stream flows from the natural falls into the ladder. • Ms. Timothy asked if the project fell under FERC jurisdiction. A review of ADNR's online water rights database on 3/18/10 did not return any record of water rights for the fish ladder. MARCH 10, 2010 PAGE 2 OF4 INDIAN RIVER PRE-APPLICATION MEETING DRAFT MEETING MINUTES POLARCONSULT ALASKA, INC. Mr. Groves replied that Polarconsult's jurisdictional analysis indicated the project was not under FERC jurisdiction. A Declaration of Intent has been filed with FERC to answer this question (docket Dil0-8-000). PERC's comment period for the DOl closes April9, 2010. • Mr. Lockard asked if any local permits would be required for the project. Mr. Bloom replied that he is not aware of any city permits that would be required beyond easements for the portions of the power line on city land. Mr. Groves mentioned that the project is not located within a state borough, so no borough- level permitting was necessary. Ms. Bohan mentioned that the project is not located within any local coastal management districts, so only the state-wide coastal management policies would be applicable. • Mr. Anderson asked if artificially enhanced fish resources received the same consideration in permitting as natural fish resources. Mr. Ferguson replied that for anadromous fish resources, the simple answer is yes. For resident fish resources, the simple answer is that it depends. • Mr. Lockard asked what type of communications were being considered for the project. Mr. Groves replied that communications were necessary between the diesel and hydro powerhouses to coordinate generation functions, and also between the hydro powerhouse and intake for head level control. Mr. Groves stated that communications could be achieved with fiber optics or copper, and the project budget assumed fiber optics. Mr. Lockard advocated for more communications capability over less, mentioning AEA's positive experiences with video capabilities at their newer rural power plants. Mr. Groves concurred, mentioning that sufficient bandwidth and power at the intake would help with project operations and could also aid the USFS' efforts to quantify salmon returns at Indian River. • Mr. Ott asked whether the project cost estimates were based on a unit installed-cost-per-kW of capacity, or if a more detailed method was used. Mr. Groves replied that the cost estimates were developed by estimating quantities for the various project elements, and applying unit costs for materials, equipment, labor, etc. The resulting estimate includes a 25% contingency. Mr. Groves stated that a more detailed cost estimate would be produced once the conceptual design was completed. • Mr. Ott (?) asked if there was equipment access between the project and Tekanee Springs, and how access logistics would be handled for project construction and operations. Mr. Groves replied that there was a well developed foot trail and suspension bridge from Tenakee Springs to the USFS road near the beach, but this was suitable only for foot traffic. Off-road vehicles can travel from Tenakee Springs to the beach landing at the USFS road along the tidelands during low tide. MARCH 10, 2010 PAGE3 OF4 INDIAN RIVER PRE-APPLICATION MEETING DRAFT MEETING MINUTES POLARCONSULT ALASKA, INC. Specific construction methods have not been decided, but generally, construction equipment and materials would be landed on the beach at the USFS road and all construction activities would be based from the USFS road and new access trails from the road to Indian River. Because the power line is located on the Tenakee Springs side oflndian River, equipment for line construction would be driven down the tidelands or moved via barge to Tenakee Springs for line construction. Construction personnel could be housed in Tenakee Springs and walk to the project site daily. Operations personnel would live in Tenakee Springs and walk to the project as needed for inspection, maintenance, and operations. If desired, a small garage could be built near the intersection ofthe walking trail and USFS road to house a vehicle(s) for project access. • Ms. Timothy(?) asked what the source of funds for the project were, and if they were already committed to the project. Mr. Groves replied that the current effort, which includes the feasibility study, conceptual design, and initial permitting, was funded with a Denali Commission grant administered by AEA. The City has also applied for additional funding through the FY 2011 round of the state's Renewable Energy Grant Program for permitting and design. The city's application was recommended for funding by AEA, but is subject to legislative approval and appropriations. The city has not started work on securing construction funding or fmancing. • Ms. Timothy mentioned that her office would develop a study plan and perform some fish trapping to assess the fish resources in Indian River. Ms. Goularte mentioned that the USFS had performed significant fisheries assessment work at Indian River in conjunction with their fish ladder project. Ms. Goularte mentioned that Mr. Perry Edwards with the USFS was familiar with their existing efforts and data. Mr. Ferguson mentioned that the USFS had completed a watershed analysis for the Indian River basin that included extensive environmental data pertinent to quantity and quality of potential fish habitat in Indian River 2 . There being no further comments or questions, Mr. Groves summarized the near-term project schedule. Polarconsult will prepare and submit permit applications for the project over the next month, and would advance conceptual designs in concert with resource agency comments over the next several months. Beyond that, the project schedule would depend on the level of effort and time necessary to secure project permits. Mr. Groves thanked attendees for their participation and adjourned the meeting at approximately 4:00PM. 2 Indian River Watershed Analysis, U.S. Department of Agriculture, U.S. Forest Service: Sitka Ranger District and Chatham Area Supervisor's Office.

CONCLUDING REMARKS PRE-APPLICATION STAKEHOLDER'S MEETING INDIAN RIVER HYDROELECTIRC PROJECT CITY OF TENAKEE SPRINGS INDIAN RIVER HYDROELECTRIC PROJECT PROJECT OVERVIEW Indian River is located approximately one mile east of Tenakee Springs. Indian River has a series of 5 barrier falls occurring between river miles 0.6 and 1.3 above tidewater. The gross head over these five barriers is I 00 feet. The mean annual flow in Indian River through these barriers is about 137 cfs. Extreme minimum flows of down to 8 cfs can occur during late summer dry spells (July -August) and the winter months (December- February). Below barrier 5, Indian River is incised into a canyon about 50 to I 00 feet deep. The canyon walls are generally steeper along the west bank (the Tenakee Springs side), and less steep along the east bank, although rock outcroppings are common along both banks through this canyon. Recommended development of Indian River's hydropower potential is with a run-of-river hydroelectric project built along the east side of the river from the top of barrier 4 to the bottom of barrier 2. This project would be located on state land, with some of the transmission line crossing city land en route to Tenakee Springs. The USFS has constructed a fish ladder to improve fish passage in Indian River at barrier 4, and has also completed fish passage enhancements at barriers 2 and 5.

On March 1, 2010, the City of Tenakee Springs filed a Declaration oflntention (DI) concerning the proposed Indian River Hydroelectric Project, which will be located near the city of Tenakee Springs, on Chichagoflsland, Sitka Borough, Alaska, affecting T. 47 S, R. 63 E, sees. 15, 21, and 22, Copper River Meridian. PROJECT DESCRIPTION 2. The proposed run-of-river Indian River Hydroelectric Project will consist of: ( 1) a 6-foot-high, 30-foot-wide diversion structure, to be located at river mile (RM) 0.85; (2) a 40-inch-diameter, 1,550-foot-long penstock; (3) a 30-foot-wide, 40-foot-long, wood frame powerhouse, located at RM 0.55, housing a 250 kW turbine-synchronous generator; (4) a 50-foot-long tailrace returning flows back into Indian River; (5) a 5,900-foot-long transmission line; and (6) appurtenant facilities. PUBLIC NOTICE 3. Notice of the DI was issued on March 9, 2010. Protests, comments, and motions to intervene were to be filed by April 9, 2010. The U.S. Department of Agriculture, U.S. Forest Service, Tongass National Forest, filed a motion to intervene and comments on April19, 2010. The comments stated that the proposed project had the potential to affect Forest Service interests, but the comments did not relate to the issue of jurisdiction. No other protests, comments, or motions to intervene have been received. JURISDICTION 4. Pursuant to Section 23(b)(l) of the Federal Power Act (FPA), 16 U.S.C. §817(1), a non-federal hydroelectric project must (unless it has a still-valid pre-1920 federal permit) be licensed if it: 20100526-3076 FERC PDF (Unofficial) 05/26/2010 Docket No. DII0-8-000 2 • is located on a navigable water of the United States; • occupies lands or reservations of the United States; • utilizes surplus water or waterpower from a government dam; or • is located on a stream over which Congress has Commerce Clause jurisdiction, is constructed or modified on or after August 26, 1935, and affects the interests of interstate or foreign commerce. DISCUSSION 5. The proposed project will not occupy any public lands or reservations of the United States and will not use surplus water or waterpower from a Federal government dam. The proposed project would be constructed after August 26, 1935, and would be located on a Commerce Clause stream. 1 However, the proposed project would not affect the interests of interstate commerce, because the City of Tenakee Springs plans to sell the generated power to the Tenakee Springs Electric Utility, which is not connected to an interstate transmission grid. Therefore, the project does not require licensing under Section 23(b )(1) of the FP A. CONCLUSION 6. Consequently, Section 23(b)(l) of the FPA does not require licensing of the proposed project. If evidence to support the Commission's licensing jurisdiction is found in the future, Section 23(b )( 1) would require licensing. Under Section 4(g) of the FP A, the project owner could then be required to apply for a license. The Director orders: (A) Section 23(b)(l) of the Federal Power Act does not require licensing of the proposed Indian River Hydroelectric Project. This order is issued without prejudice to any future determination upon new or additional evidence that licensing is required. 1 The Indian River flows into Tenakee Inlet and Chatham Straits, tributary to the Pacific Ocean. 20100526-3076 FERC PDF (Unofficial) 05/26/2010 Docket No. Dll0-8-000 3 (B) This order constitutes final agency action. Requests for rehearing by the Commission may be filed within 30 days ofthe date of issuance ofthis order, pursuant to 18 C.F.R. § 385.713.

The project would include the following major components: An intake structure consisting of an approximately 6-foot tall by 30-foot wide diversion structure spanning the creek near or adjacent to an existing USFS fish ladder located approximately at river mile 0.85. Apparatus to remove debris from the project water would either be incorporated into the diversion structure or constructed on uplands immediately adjacent to the diversion structure. The diversion structure would direct up to 80 cfs of water into a approximately 1,550 foot long penstock. The project would have a gross head of approximately 60 feet, and net head of approximately 50 feet. The project powerhouse would be located adjacent to Indian River at approximately river mile 0.55, and would house a crossflow turbine, synchronous generator, switchgear, controls, and related equipment. The tailrace would return flows back to Indian River. The project would generate approximately 1,500,000 kWh of energy annually, which would be transmitted to Tenakee Springs via an approximately 5,900 foot long three-phase 7.2kV power line. This project is a run-of- river project so there is no storage capacity. MAPS A Location Map and Project Map are attached on the following pages. The Location Map shows the general project location in Alaska, and the Project Map shows, in detail, the proposed locations of project features and location of federal, state and municipal land in the project vicinity. RIVER DURATION CURVE AND HYDROGRAPH Because this project is run-of-river, it has no storage or modification of flows downstream of the project. Therefore, only the flow duration curve and the stream hydrograph are shown. The curves are attached on the following pages. Hydrology data is derived from seven years of USGS stream flow data for Indian River, augmented by additional USGS data from nearby drainages with similar hydrology. JURISDICTIONAL ANALYSIS Navigability of the stream Indian River is not a navigable stream. Land Status The project lands are owned by the State of Alaska and the City of Tenakee Springs. Lands affected by the project are shown in the Project Map. Government Dam The project does not utilize waterpower from a Government Dam Interstate Commerce The project does not affect interstate commerce. Power from the project will be sold by Tenakee Springs Electric Utility to its customers located in Tenakee Springs.

Your information is well organized and easy to follow. I'll be reviewing the entire project under Nationwide Permit #17 Hydro Projects. We won't need to separate out by utility/roads etc. I've just finish reviewing it and have the following items that need additional clarification/information: Wetlands Delineation 1) send data sheets that determined the delineation 2) Include the methods used to determine the mosaic along with field notes to determine the ratios submitted. Site Plans 1) Include the potential landing sites for landing the equipment/materials ie; L TF and/or the beach access. Include the eel grass beds that you described near the beach access. HTL and MHW mark too. Project Access Roads 1) The description of the access road (the last 250 feet) station 18-20.50. You describe an estimated 250 cubic yards of fill into 1, 700 sq. ft of wetlands. I believe the fill would be below the OHWM oflndian River. Please clarify. 2) Will any of the roads be removed post installation? Powerhouse 1) How many cubic yards of material will be blasted in Indian River to establish the final grade of the tailrace channel? 2) Will sedimentation measures be used during blasting? 3) How much sheet pile and/or concrete will be required to stabilize between the powerhouse and OWHM of Indian River? Power Line 1 )The narrative indicates up to 15% of the power line would be located in uplands. Additionally a stream crossing would be required. Does the amount of fill include the stream crossing to bed the culvert? If so, reduce the wetlands fill and add to a category called waters of the U.S. (essentially below the ordinary high water line of a water body) Show the flow of water in the drawing too.

The hydroelectric project will supply an estimated 90% of Tenakee Springs' electricity/ eliminating approximately 31,000 gallons of fuel shipments to the community annually. The project will help to lower the extremely high price of electricity in the community. This letter report provides the following: 1. Documentation of wetland investigations and delineations performed to quantify wetlands impacts associated with project construction. 2. Provides a summary of the hydro project features and the wetland impacts associated with each feature. 3. Provides a description of the design modifications and strategies used to avoid, minimize1 and mitigate wetlands impacts associated with construction of this project. Hydro project features, footprints, and alignments described in this letter report are based upon the conceptual design drawings for the project prepared by Polarconsult and dated July 29 1 2011. These conceptual design drawings replace an earlier plan set completed April 14, 2011. The newer conceptual designs reflect revisions to the project that have been made to avoid and minimize wetlands impacts. The conceptual design described herein reflects the current development concept for the project, based on available technical and environmental information. These designs are subject to change as necessitated by economic, technical, environmental, and other factors as this project continues through the design and permitting process. 110809-WETLANDLETIERREPORT.DOC INDIAN RIVER HYDROELECTRIC PROJECT WETLANDS DELINEATION LETTER REPORT POLARCONSULT ALASKA, INC. AUGUST 9, 2011 1.2 Project Site The Indian River hydroelectric project site is located approximately one mile east of Tenakee Springs, Alaska on a combination of city and state land. The site is located within Sections 15, 21, and 22 of Township 47 South, Range 63 East, Copper River Meridian (see Permit Drawings). The project site totals approximately 4.23 acres (Table 1). Table 1: Summary of Project Area and Wetland Impacts by Project Feature Feature Total Area Area of Wetland Impact Volume of Wetland (acres) (square feet) Fill (cubic yards) Access Roads 2.00 Along intake access road: 7,000 1,000 Diversion I Intake 0.03 Diversion/Intake footprint: 1,000 1 100 1 Penstock 0.60 Trestle piers, on grade penstock: 1,500 100 Powerhouse Site 0.10 Powerhouse footprint: 3,000 1 700 1 Power Line 1.50 sta. 24+00 culvert crossing: 600 so incidental other (microsites): 9,200 750 TOTAL 4.23 18,300 + 4,000 1 = 22,300 1,9oo I 800 1 = 2,100 Wetland Impact Area Under NWP #12 for Utility Lines 9,800 SF (0.23 ac) Wetland Impact Area Under NWP #14 for Access Roads 7,000 SF (0.16 ac) Wetland Impact Area Under NWP #17 for Hydropower Projects 5,500 SF (0.13 ac) 1. Fill below ordinary high water line in Indian River The project site will be accessed from an existing U.S. Forest Service logging road (Road No. 7500) via approximately 3,200 feet of new access roads and/or trails. The project will feature a diversion and intake structure at an elevation of 120 feet on Indian River. This structure will be co-located with an existing fish pass built and maintained by the U.S Forest Service to establish a coho salmon population on Indian River. Up to 50 cubic feet per second (cfs) of water will be conveyed from the intake structure down to the powerhouse building via approximately 1,550 feet of penstock (pipeline). This penstock will be supported on trestles and located along and/or above the bank of Indian River. Approximately 4,000 feet of power line will connect the hydro powerhouse with the city's existing electric distribution system. The power line will cross Indian River overhead, and will run underground to connect with the existing overhead system near the small boat harbor. A small trail will be built along the power line route to provide access from Tenakee Springs for construction, inspection, maintenance, and repair of this power line. The project will not be directly accessible from this trail due to Indian River Canyon. PAGE 2 OF 9 INDIAN RIVER HYDROELECTRIC PROJECT WETLANDS DELINEATION LETTER REPORT POLARCONSULT ALASKA, INC. AUGUST 9, 2011 1.3 Wetland Delineation Methods The wetlands delineation for this project was completed using a Routine Level 3 delineation method, as set forth in the Corps of Engineers Wetlands Manual 1 and Alaska Supplement2 . The delineation relied on a combination of existing site information, new site information obtained for this project, and on-site wetland determinations in areas where existing information lacked sufficient detail to complete delineations at the mapping scales necessary for this project. Wetland determinations in the field were made using hydrophytic vegetation and wetlands hydrology assessment. Soil pits were not feasible during the April 2011 site visit due to frozen ground. In order to avoid misclassification of wetlands as uplands, hydric soils were assumed to exist at sites where the Wetlands Manual calls for the identification of hydric soils to make a wetland determination. The result of this approach is a conservative wetlands delineation for the project area. 1.4 Summary of Information and Investigations First, available existing information sources for the project site were obtained. Existing information includes: ~ U.S. Geological Survey (USGS) 1:63,360 scale topographic maps of the project area, 3 ~ Visible-band aerial color imagery of the project area, 4 ~ Infrared-band aerial color imagery of the project area, 5 ~ National Resource Conservation Service (NRCS) soil survey of the project area, 6 ~ National Wetlands Inventory (NWI) database, 7 ~ Corps of Engineers investigations letter report for Indian River Hydroelectric Project, 8 ~ Final Environmental Impact Statement (EIS) for Indian River Timber Sales, 9 and ~ Indian River Watershed Analysis. 10 1 Environmental Laboratory. 1987.

AUGUST 9, 2011 This information was supplemented with two field visits to the project site. Due to the remote project location, wetlands delineation field work was conducted concurrently with project evaluation and conceptual design efforts to economize on cost. Polarconsult engineers Joel Groves, PE and Michael Dahl, PE conducted initial field investigations from June 1 through June 3, 2009. Mr. Groves and Mr. Dahl were accompanied in the field by Mr. Art Bloom, the project manager for the City of Tenakee Springs. This field investigation was conducted to evaluate the project site for constructability; evaluate potential power, penstock, and access alignments; review proposed diversion/intake and powerhouse sites; and assess the presence of wetlands in the project vicinity. During this site visit, limited aerial reconnaissance of the project area was also completed. Field observations were used to develop the November 2009 feasibility study for the hydroelectric project. Subsequent to this field visit and completion of the project feasibility study, a UDAR topographic survey of the project area was performed in April 2010 by Aero-Metric U.S., Inc. The UDAR survey produced two-foot contours and a reflectivity map of the project area. Based on this data, a conceptual project design was completed April 14, 2011. Mr. Groves conducted additional field investigations from April 17 to 23, 2011. Mr. Groves was accompanied in the field by Mr. Bloom on this second field visit. Field activities in April 2011 included wetlands delineations in the project footprint, verification of the UDAR survey data in key areas, additional topographic surveys in key project locations, and a field review of the conceptual design for general constructibility and compatibility with environmental conditions in the project area. The April 2011 conceptual designs were revised to reflect field findings, and a new set of conceptual designs completed July 29, 2011. 2.0 SUMMARY OF WETLANDS INDICATOR INFORMATION 2.1 Summarv of Information on Hvdrophytic Veaetation The Indian River Timber Sale EIS, NWI database, and NRCS soil mapping datasets provide consistent overviews of vegetation in the project area at a 1:24,000 scale. These characterizations are consistent with field observations and aerial imagery. Small sites within the project area not captured by 1:24,000 scale mapping (sites from approximately 1,000 to 10,000 square feet) were also identified and mapped during field visits. 2.2 Summary of Information on Wetlands Hydrology The Indian River Timber Sale EIS and NRCS soil mapping dataset both provide a general narrative of site hydrology. This data is augmented with the detailed topographic mapping completed for this project and field observations. Field efforts in the project area focused on mapping small sites (approximately 1,000 to 10,000 square feet) not identified by previous mapping efforts. PAGE40F9 INDIAN RIVER HYDROELECTRIC PROJECT WETLANDS DELINEATION LETTER REPORT POLARCONSULT ALASKA, INC. AUGUST 9, 2011 2.3 Summary of Information on Hydric Soils Test pits were not feasible during the April 2011 site visit because the ground was still frozen. Information in the NRCS soils database and naturally exposed soil profiles in the project area are used to guide assessment of hydric soils. Where this data is insufficient, hydric soils are assumed to be present at candidate wetland sites. 3.0 DESCRIPTION OF PROJECT FEATURES AND WETLAND IMPACTS 3.1 Beach Landing Sites tor Proiect Equipment and Materials Materials and equipment for the project will be landed at two locations: (1) Materials for the hydro project will be landed at or near the existing log dump site at the beginning of Indian River Road. Two options are possible here. There is an existing shot rock pier that extends into the upper intertidal zone that was used for logging operations at Indian River in the early 1980s. There is also a spur road that ends at the beach just west of the pier. The beach at this location is comprised of broken rock and gravel, and is suitable to land a barge for materials and equipment offload. The lower intertidal zone in this area is populated by eel grass beds, so any landings at this site would need to coordinate with high tides to avoid beaching the barge or maneuvering in the eel grass beds. There is ample room in the upper intertidal zone for this. The beach in this area transitions from gravels into bedrock and forested uplands. There are no wetlands in the immediate area above the tidal zone. (2) Materials for the power line between the hydro project and Tenakee Springs will be landed in the vicinity of the small boat harbor in Tenakee Springs. The beach in this area is gravel with occasional large rocks and bedrock outcroppings. The upper intertidal zone is devoid of vegetation, but vegetation is increasingly present moving towards the low tide line. There is ample room to land a barge and offload materials and equipment. There are no wetlands in the immediate area above the intertidal zone. No wetlands impacts are identified from beach landings required for this project. There are no practical alternatives to beach landings to deliver the materials and equipment necessary to construct this project. No permanent improvements are proposed for the barge landing sites associated with this project. 3.2 Project Access Roads The main access route to the hydro powerhouse will be a 10 to 16-foot wide construction road extending from the existing U.S. Forest Service road down to the Indian River powerhouse. The road will be built with local materials using balanced cut and fill, and capped with geofabric and/or gravel where necessary. PAGE50F9 INDIAN RIVER HYDROELECTRIC PROJECT WETLANDS DELINEATION LETTER REPORT POLARCONSULT ALASKA, INC. AUGUST 9, 2011 The first approximately 750 feet of this road (station 0+00 to 7+50) crosses uplands that slope uniformly down towards Indian River at approximately 8%. This upland area is vegetated by mature conifer forest. This portion of the access road does not cross any wetlands or streams. The next approximately 850 feet of the access road (station 7+50 to 16+00) climbs a 20-foot tall embankment and follows the top of this embankment towards the powerhouse. This area is uplands, populated by mature conifer forest and deciduous brush. Forested wetlands are present in some areas along the toe of this embankment. The access route has been positioned away from the rim of this embankment to avoid any disturbance of these wetlands. This portion of the access road does not cross any wetlands or streams. The next approximately 200 feet of the access road (station 16+00 to 18+00) is a steep grade descending approximately 90 feet down the fall-line into Indian River Canyon. This is suitable only for passage of tracked equipment or winch operations. This grade ends on a uplands bench approximately 30 feet above Indian River. An approximately 3,600 square foot staging area will be built on this bench for powerhouse construction. This bench is vegetated with mature conifer forest. The northern end of this bench becomes increasingly brushy, and eventually transitions into a forested wetland. This portion of the access road and the staging area does not impact any wetlands or streams. The last approximately 250 feet of the access road (station 18+00 to 20+50) is a 10 to 14-foot wide access trail descending at 20% grade down to the powerhouse in the canyon. This road will be built on structural fill the toe of which will partially extend into Indian River in the immediate vicinity ofthe powerhouse. A sheet pile and/or concrete retaining wall will limit the footprint of this structural fill in Indian River and protect the fill from flood flows and erosion. Vegetation in this area is a combination of barren rock slopes/slides and vegetation (mostly alder with some willow and devil's club) near Indian River. Some conifer forest is present in less steep areas from approximately station 18+00 to 19+00. An estimated 250 cubic yards of fill into 1,700 square feet of wetlands are associated with this access road. A spur road will depart from the main access road at station 7+50 and head to the intake site. This road will have the same dimensions and construction as the main access road. The first approximately 900 feet of the intake road (station 0+00 to 9+00) will be located on moderate side slopes above the rim of Indian River Canyon. This road passes along the edge of a forested uplands/wetlands complex that is 50% upland I 50% wetland, and vegetated by mature conifers with deciduous under story brush. The last approximately 190 feet of the intake road (station 9+00 to 10+90) passes through a forested wetland (mixed conifer/deciduous canopy with brush and devil's club in the under PAGE 6 OF 9 INDIAN RIVER HYDROELECTRIC PROJECT WETLANDS DELINEATION LETTER REPORT POLARCONSULT ALASKA, INC. AUGUST 9, 2011 story) located on a bench above Indian River. This portion of the access road has been narrowed to a width of 10 to 14 feet to reduce wetland impacts. An 18-inch diameter culvert will be installed at station 10+60 to pass discharge from this wetland under the access road. The road is estimated to require 750 cubic yards of fill into 5,300 square feet of wetlands. Alternative methods to access the intake were evaluated and all are considered impractical for cost, logistic, and long term sustainability reasons. Permanent vehicular access to the intake is necessary for operations, maintenance, and repair, and will also reduce construction costs. Two short construction trail spurs are proposed off the intake access road to the rim of the Indian River Canyon to facilitate penstock construction. Both roads would be 10-foot wide temporary construction trails built of native material and used to transport penstock materials to the penstock alignment. Neither road passes through wetlands. All of these access alignments were evaluated on foot during the June 2009 and/or April 2011 field work. Wetlands delineations and impacted areas are indicated on the July 29, 2011 conceptual design drawings and August 9, 2011 Corps of Engineers permit drawings. The April14, 2011 conceptual design called for the access road to the powerhouse to be built at an approximately 15% grade. This required a bench to be built in Indian River Canyon for approximately 980 feet. This configuration would have required significant earth work and blasting, resulting in increased discharge of some of the spoils into Indian River and wetlands along this route. The April 2011 field work identified slope stability, cost, and environmental concerns with this approach. The currently proposed design with a steep track/winch line avoids these impacts. 3.3 Diversion I Intake Structure The proposed diversion and intake structure will be co-located with the existing concrete fish pass at barrier 4 on the west side of Indian River. The intake structure will add a new taller head wall and two additional fish cells to the top of the existing fish pass, as well as a hydro intake and a weir across Indian River. The head wall and water inlets will be designed to preferentially direct low flows first into the fish pass, second into the hydro intake, and third over the weir and into Indian River. The hydro intake will be built adjacent and parallel to the fish pass structure. The intake will utilize a coanda-effect inclined plate screen to filter debris out of the penstock and to allow all life stages of fish to pass over the screen and into Indian River. Except for the east end of the weir wing wall, the intake and diversion structure is located below the ordinary high water line of Indian River. The structure's footprint is devoid of vegetation and is mostly bedrock. Some areas have a thin mantle of gravels over bedrock. PAGE 7 OF 9 INDIAN RIVER HYDROELECTRIC PROJECT WETLANDS DELINEATION LETTER REPORT POLARCONSULT ALASKA, INC. AUGUST 9, 2011 The diversion structure will require approximately 100 cubic yards of fill into 1,000 square feet below the ordinary high water line of Indian River. 3.4 Penstock The penstock alignment extends along the floor of Indian River Canyon for approximately 1,225 feet downstream from the intake structure (station 0+36 to 12+62). This portion of the penstock is built above grade with trestles supporting the pipe every 20 feet. The trestles will be supported by concrete or steel piers. Most of these piers will be founded on bedrock above the ordinary high water mark of Indian River. Piers located below the ordinary high water mark or within flood velocity hazard areas may include additional civil works to protect them from flood damage. The penstock alignment in this area is comprised of bedrock or a thin mantle of gravels and cobbles over bedrock. When present, vegetation is generally a combination of alders, willows, and sometimes devil's club. The last 325 feet of the penstock will be built on grade or buried. Approximately 90 feet (station 12+62 to 13+50) will be built on cribs installed on grade through a forested wetland (conifer forest with deciduous under story and devil's club). The remaining approximately 235 feet or the penstock alignment will be located in forested uplands and will be on grade or buried. The penstock will require approximately 100 cubic yards of fill into 1,500 square feet of wetlands and/or areas below the ordinary high water line of Indian River. The Aprill4, 2011 conceptual design called for the penstock to be installed on a trestle system along the east side of Indian River running at a 2% grade from the intake down to the powerhouse. This configuration would have required significant earth work and blasting, resulting in increased discharge of spoils into Indian River and wetlands along the route. The April field work identified slope stability, cost, and environmental concerns with this approach. The currently proposed trestle design avoids and/or minimizes these impacts. 3.5 Powerhouse The powerhouse will be located on fill placed partially below the ordinary high water mark on the east side of Indian River immediately downstream of falls #2. Soils at the powerhouse site are a combination of exposed bedrock and shallow gravel deposits over bedrock. Vegetation is not present below the ordinary high water line. A sheet pile and/or concrete retaining wall will be installed between the powerhouse site and Indian River to protect the powerhouse site from floods and erosion. This is the same wall associated with the access road to the powerhouse (Section 3.2). The tailrace channel and powerhouse foundation will be integral to this retaining wall. Blasting in Indian River will be required to establish the final grade of the tailrace channel. PAGE 80F 9 INDIAN RIVER HYDROElECTRIC PROJECT WETlANDS DELINEATION LETTER REPORT POLARCONSULT ALASKA, INC. AUGUST 9, 2011 No cut slopes are proposed in the canyon wall at the powerhouse site to avoid compromising the stability of the canyon slopes above the powerhouse. The powerhouse site will require approximately 700 cubic yards of fill placed in 3,000 square feet below the ordinary high water line of Indian River. The powerhouse site was moved upriver approximately 140 feet from the location in the April 14, 2011 conceptual design drawings. This revision was implemented for the following reasons: ~ The upriver site reduces the fill area below the ordinary high water line. ~ The canyon slopes at the upriver site appear to be more stable. ~ The upriver site is more compatible with river hydraulics than the original site. ~ The upriver site does not diminish the project's technical or economic performance. 3.6 Power Line The power line for the project will start at the small boat harbor and continue underground for approximately 3,850 feet to the west rim of Indian River Canyon. It will cross Indian River overhead and terminate at the powerhouse at approximately station 40+14. The power line route traverses sidehill country that is vegetated by conifer forest with deciduous understory in some areas. Several large emergent wetlands with forested wetland buffers in this area are identified in NWI, NRCS, and USFS information, and are apparent in aerial imagery and detailed topographic maps. The power line route avoids these areas. A small creek that drains this wetland area is crossed at station 22+00 with a 24-inch culvert. A maintenance trail will be co-located with the buried power line to allow inspection, maintenance, and repair of the power line. The trail will be 6 to 8 feet wide, and built of native materials. Vehicular access to the powerhouse will not be possible along the power line route due to Indian River Canyon. There are several small wetlands created by micro topography along the power line route that were not mapped in detail during field investigations. There is sufficient flexibility in the power line alignment to avoid impacting many of these small wetland areas. Fifteen percent of the total power line footprint is assumed to require wetlands fill. Based upon field review of the power line alignment, this is a very conservative allowance. The power line will require approximately 800 cubic yards of fill into 9,800 square feet of wetlands. PAGE 9 OF9 Joel Groves From: "Speerstra, Linda POA" <Linda.Speerstra@usace.army.mil> Date: Friday, December 17, 2010 10:48 AM To: <joel@polarconsult.net> Subject: Tenakee Springs Hydro Hi Joel. I'm almost back from leave. I do have some additional questions on the Hydro Project in Tenakee POA-20 10-0758. I'll list them below: 1) How many crossings will be needed on the 3200' road? What is the width of the road? Also, cubic yards of material necessary to bed the two crossings indicated. What is the size of the culverts? If the road is crossing any wetland areas the acreage and fill material will need to be tallied. If you aren't crossing wetlands state that in your narrative/application. Figure 2 of 5 indicates that the road to the intake will cross the top of a wetland area. 2) Will the penstock be bedded underground or in the stream? Figure 3 shows the intake structure with the penstock incased in something. Is the encasement concrete? Can you send me additional information on the intake unit with dimensions and type of material for each component. 3) How much riprap will be used and placed in the stream for the hydro unit placement? I need specific information on amounts of fill material and area of impact broken out by intake, powerhouse, penstock, road, trail, access area, etc. 4) Figure 4 Powerhouse indicates wetlands along the OHW. I'll need quantities for this location also. What is the deflector wall made of? You'll need to label river bank as OHW if that is what it is. 5) The compensatory mitigation measures described our minimization measures. Are you proposing compensatory mitigation? Bullet number 2 in compensatory mitigation discusses a coordinated effort with USFS and ADF&G. I would need more description on the enhancement work that would increase the functionality of the fish passage. Send drawings and pictures for the proposal. 6)I need drawings for the access trail, penstock at location determined, staging area for equipment, etc. 7) the CPQ indicated there will be fill in Section 10 waters (marine waters) is there a proposal for a staging area along the beach? I'm sure you'll have some questions. So please give me a call. I'm in the Juneau Field Office today 790-4490. I'll be back in the Sitka Field Office on Monday. Joel, if you have pictures of the area that would help a bunch. It's been years since I've been in Tenakee. If you have a field trip planned for the Page 1 of2 9/16/2011 spring please let me know and I'll tag along. Linda Linda Speerstra Regulatory Specialist Sitka Field Office P.O.

The final mitigation rule was published in the federal register on AprillO, 2008, and became effective on June 9, 2008. The final rule establishes standards and criteria for the use of appropriate and practicable compensatory mitigation for unavoidable functional losses of aquatic resources authorized by Corps permits (33 CFR Part 332). Additionally, the rule requires new information to be included in Corps permit applications and public notices to enable meaningful comments on applicant proposed mitigation. In accordance with 33 CFR Part 325.1(d)(7), "For activities involving discharges of dredged or fill material into waters of the U.S., the application must include a statement describing how impacts to waters of the United States are to be avoided and minimized. The application must also include either a statement describing how impacts to waters of the United States are to be compensated for or a statement explaining why compensatory mitigation should not be required for the proposed impacts." For additional information, the final mitigation rule can be viewed at: http://www. usace.army.mil!cw /cecwo/reg/news/final_ mitig_ rule. pdf Mitigation is a sequential process of avoidance, minimization, and compensation. Compensatory mitigation is not considered until after all appropriate and practicable steps have been taken to first avoid and then minimize adverse impacts to the aquatic ecosystem. Please provide your proposed avoidance, minimization, and compensatory mitigation below: Applicant's Proposed Mitigation (attach additional sheets as necessary): 1. Avoidance of impacts to waters of the U.S., including wetlands: Please describe how, in your project planning process, you avoided impacts to waters of the US, including wetlands, to the maximum extent practicable. Examples of avoidance measures include site selection, routes, design configurations, etc ... Project features such as access roads, penstock, and trails will be routed to avoid wetlands and minor drainages where technically and economically feasible. 2. Minimization of unavoidable impacts to waters of the U.S., including wetlands: Please describe how your project design incorporates measures that minimize the unavoidable impacts to waters of the US, including wetlands, by limiting jill discharges to the minimum amount/size necessary to achieve the project purpose. Where fill of wetlands/waters or crossing of minor drainages cannot be avoided, such as at the intake, powerhouse, and other locations, the design of these features will minimize the impact to wetlands and waters. The powerhouse site will use a combination of rip-rap, retaining walls, piling, or other methods to minimize the powerhouse site footprint. The intake will be a concrete or similar structure built in a section of Indian River that flows over bedrock and cobbles, minimizing habitat loss relative to other intake sites. Access features will use culverts or other means as appropriate to cross minor drainages with minimal disruption of drainage patterns. 1 Applicant Proposed Mitigation Statements 3. Compensation for unavoidable impacts to waters of the U.S., including wetlands: Please describe your proposed compensatory mitigation to offset unavoidable impacts to waters of the US., or, alternatively, why compensatory mitigation is not appropriate or practicable for your project. Compensatory mitigation involves actions taken to offset unavoidable adverse impacts to waters of the US., including wetlands, streams and other aquatic resources (aquatic sites) authorized by Corps permits. Compensatory mitigation may involve the restoration, enhancement, establishment (creation), and/or the preservation of aquatic sites. The three mechanisms for providing compensatory mitigation are mitigation banks, in-lieu fee of mitigation, and permittee-responsible mitigation. Please see the attached definitions for additional information. Unavoidable impacts will be mitigated by one or more of the following measures: • Impacts along the banks of Indian River at the intake and powerhouse sites will be mitigated by revegetating the banks in these areas after construction. Typical existing bank-edge vegetation includes alders, willows, and devil's club, and these sites are deemed to be excellent candidates for successful revegetation. • Design of the project will be coordinated with USFS and ADFG to complement and where practicable enhance the functionality of the fish passage improvements USFS has constructed on Indian River. This mitigation effort will help support enhancement of the biological productivity of the resource. 2 Applicant Proposed Mitigation Statements Definitions: Enhancement: the manipulation of the physical, chemical, or biological characteristics of an aquatic resource to heighten, intensity, or improve a specific aquatic resource function(s). Enhancement results in the gain of selected aquatic resource function( s ), but may also lead to a decline in other aquatic resource function(s). Enhancement does not result in a gain in aquatic resource area. Establishment (creation): the manipulation of the physical, chemical, or biological characteristics present to develop an aquatic resource that did not previously exist at an upland site. Establishment results in a gain in aquatic resource area and functions. In-lieu fee program: a program involving the restoration, establishment, enhancement, and/or preservation of aquatic resources through funds paid to a governmental or non-profit natural resources management entity to satisfY compensatory mitigation requirements for DA permits. Similar to a mitigation bank, an in-lieu fee program sells compensatory mitigation credits to permittees whose obligation to provide compensatory mitigation is then transferred to the in-lieu program sponsor. However, the rules governing the operation and use of in-lieu fee programs are somewhat different from the rules governing operation and use of mitigation banks. The operation and use of an in-lieu fee program are governed by an in-lieu fee program instrument. Mitigation bank: a site, or suite of sites, where resources (e.g., wetlands, streams, riparian areas) are restored, established, enhanced, and/or preserved for the purpose of providing compensatory mitigation for impacts authorized by DA permits. In general, a mitigation bank sells compensatory mitigation credits to permittees whose obligation to provide compensatory mitigation is then transferred to the mitigation bank sponsor. The operation and use of a mitigation bank are governed by a mitigation banking instrument. Permittee-responsible mitigation: an aquatic resource restoration, establishment, enhancement, and/or preservation activity undertaken by the permittee (or an authorized agent or contractor) to provide compensatory mitigation for which the permittee retains full responsibility. Practicable: available and capable of being done after taking into consideration cost, existing technology, and logistics in light of overall project purposes. Preservation: the removal of a threat to, or preventing the decline of, aquatic resources by an action in or near those aquatic resources. This term includes activities commonly associated with the protection and maintenance of aquatic resources through the implementation of appropriate legal and physical mechanisms. Preservation does not result in a gain of aquatic resource area or functions. Restoration: the manipulation of the physical, chemical, or biological characteristics of a site with the goal of returning natural/historic functions to a former or degraded aquatic resource. For the purpose of tracking net gains in aquatic resource area, restoration is divided into two categories: re-establishment and rehabilitation. 3 polarconsult alaska, inc.

Things she needs: 1. Wetlands delineation. Not shown on maps. Told her we had a good idea of where they are based on past field trips, topo, and aerial imagery, but a formal delineation hasn't been done. She said this would work on a preliminary basis and she would check with her supervisor on if this was sufficient generally. I mentioned that we did plan to mobe out again and could do the wetlands at that time. She asked of schedule, I said I wanted to receive all the comments from permitting agencies and then do a site visit to collect what data is necessary. Not sure if that will happen this fall or in the spring. She would like to accompany us on the visit if possible. 2. Road plan. She needs to see stream crossings, drainages, etc. 3. Mitigation Plan. There is a form for the PCN. I didn't see this. 4. Details on the 4,500' trail. There are a number ofNWPs that can be used for the project, so split it and impacts out into the hydro, the access route, and the utility corridor. That will help increase the minimums. She will email the Mitigation Plan form and recap the discussion. • . ' . polarconsult alaska, inc .

RESTORATION/ REVEGETATION PLAN PREPARED BY POLARCONSUL T ALASKA, INC AUGUST2010 Below the project, the first half-mile of Indian River is a low gradient stream running at approximately 0.6%. This reach supports pink and chum salmon. From River mile 0.5 to 1.0, Indian River has an average gradient of about 2.7%, but drops through a series of five significant waterfalls or fish barriers. This is where the hydro project will be located. The value of this reach of the river as fish habitat is understood to be primarily as a migration corridor to upstream rearing and spawning habitat. Several past USFS projects have improved fish passage around the barrier waterfalls. The project will be designed to strike a balance between the need to control construction and operating costs and minimize impacts on fish habitat. Topography in the project area requires that the penstock and powerhouse will be located within the Indian River Canyon. This will require some trail work within the canyon, including blasting, which will generate some potential for erosion and sediment transport. Stormwater prevention measures will be used to control sediment transport. Generally, it is less costly and superior ecologically to avoid habitat impacts rather than restore or mitigate them. By close consultation with ADFG and USFS, the City of Tenakee Springs intends to create a realistic project design and construction approach for the hydro project. Primary project objectives with regard to fish habitat protection are expected to include: .. Avoid formation of new migration barriers along project reach. .. A void excessive sedimentation of downstream habitat areas. .. A void excessive degradation of stream bank vegetation. Each of these is briefly discussed below. Avoid Formation Of New Migration Barriers Migration barriers may be formed by: .. Reduction of flows in the bypass reach. It is unknown if reducing flows in the bypass reach will improve or impede fish passage. Reduced flows may eliminate existing velocity barriers. The USFS has established a minimum flow requirement for their fish ladder around barrier 4 of 10 cfs, which will also be available through the entire hydro bypass reach. Natural flows at the fish ladder exceed 10 cfs 99% of the time. The city proposes to design and operate the hydro project in a manner that maintains minimum flows through the fish ladder and bypass reach during critical migration seasons. Natural low flow periods occur during December through February and in late July through mid-September. .. Creation of new barriers by deposit of waste rock or fill into Indian River. Project construction will result in some placement of fill into Indian River. The volume, type, and location of fill will be determined through the design and permitting process. Avoid Excessive Sedimentation Of Downstream Habitat Areas Excessive sedimentation of downstream habitat areas will be avoided by: PAGE3 OF4 CITY OF TENAKEE SPRINGS ELECTRIC UTILITY DEPARTMENT INDIAN RIVER HYDROELECTRIC PROJECT FISH HABITAT PERMIT ATTACHMENTS PREPARED BY POLARCONSUL T ALASKA, INC AUGUST2010 'lll Project design to minimize generation of top soil, exposed cuts, and related civil works with erosion potentiaL 'lll Avoiding disposal oftop soil and fines into Indian River. 'lll Use of silt fences and similar storm water control measures to trap sediment. 'lll Revegetating cleared areas to reduce long-term erosion potentiaL A void Excessive Degradation Of Stream Bank Vegetation Excessive degradation of stream bank vegetation will be avoided by: 'lll A voiding construction activities on the stream bank. 'lll Restoring vegetation along disturbed areas of the stream bank. The stream bank in the project area is typically vegetated by a variety of willows, devil's club, and similar fast-growing plants. The potential for successful revegetation of disturbed areas of the stream bank is considered to be very good.

(Polarconsult) that the U.S. Forest Service (USFS) plans to transfer approximately 20 miles of Indian River Road (USFS road 7500, 'IRR') into storage during the summer of 2012. As described in the USFS' request for proposals that was published July 291h, 2011, this project will involve replacing culverts and bridges along the road with hardened water crossings or off-highway vehicle (OHV) rated bridges. As the USFS is aware, Tenakee is actively pursuing a run-of-river hydroelectric project on Indian River, which is currently in the design and permitting phase. Tenakee expects the hydro project will be ready for construction in the summer of 2013. The project conceptual design, construction plan, and capital cost estimate all rely upon using the first approximately 1.3 miles of IRR for heavy equipment and light vehicle access to the project during construction and also for operations, maintenance, repair, and replacement (OMRR) activities over the life of the project. As advertised, it appears the IRR storage project will render IRR impassable to heavy equipment, requiring the city to either restore the road to a serviceable condition or employ more costly construction and OMRR methods. Either option will increase project costs, jeopardizing the project's economic viability and potentially forcing Tenakee to continue to rely on expensive diesel fuel for power generation. Tenakee formally requests that the USFS modify its IRR storage project such that the portion of IRR needed to access the project remain passable to heavy equipment and vehicular traffic. Tenakee is amenable to working with the USFS to reallocate avoided storage project costs to road rehabilitation and develop a reasonable plan for long term maintenance of the segment of IRR needed for hydro project access. Polarconsult has provided the USFS with conceptual designs that detail the location of the hydro access route and overall design of the project, and will continue to coordinate with the USFS on road use plans and permits necessary for use of IRR for this project.

Work includes installing waterbars, excavating and sidecasting road fill material, removing culverts and log bridges, removing modular bridges and transporting them to Thome Bay, Alaska, removing 2 abandoned vehicles, constructing a log stringer trail bridge, clearing brush from the roadway for equipment access, and seeding and fertilizing exposed organic soils on and along roadsides on approximately 20 miles of National Forest System Roads on Chichagoflsland. The removed culverts and hardware become the property of the contractor and must be removed from the National Forest. The Contractor shall furnish all labor, materials, equipment, tools, transportation, supplies, and perform all work required to maintain the facilities in accordance with the attached typical drawings, supplemental specifications and parent specifications. Road storage work in this contract involves stabilizing roads regarding drainage. Work will include a combination of drainage structure removal, waterbar construction, clearing the roadway of brush for project access and proper drainage, and seeding and fertilizing bare organic soils. Road storage work is payable on a per mile basis, regardless of the number of drainage structures removed or constructed for each mile, and the amount of seeding and fertilizing required. Approximately 9 miles of road storage will construct waterbars and fords for off highway type vehicle (OHV) passage at locations where culverts and bridges are removed, and at additional staked locations. The remaining 11 miles of road storage will not be left open to OHVs, these roads will have structures removed, waterbars constructed and be blocked to motorized vehicles with a barrier of rock borrow and logs. Spacing between waterbars will be 50 to 750 feet apart on each type of road storage. Refer to the drawings and worklist in Section J for details on each project road. The work includes removing and transporting modular steel bridges from the work area to the Thome Bay, Alaska sortyard. Moving the bridges on the Indian River road system may require additional work on the existing native log bridges, which were constructed in the late 1970s. Several bridges have undermined sill logs due to stream scour, and many have visible rot in the brow logs. The modular bridge furthest from the beach, a 70' Hamilton at MP 13.273 on road 7500 is located beyond a site where a log bridge has been previously removed. The span of the removed log bridge was 70' and it sat on log crib abutments approximately 15' above the stream elevation. Mobilizing beyond the removed log bridge site may involve construction of a temporary bridge provided by the Contractor, or it may involve additional excavation of the rock borrow approaches to allow equipment access through the stream and beyond the site. A site visit to the work area is recommended, the road leading to the removed log bridge site is presently open and drivable to OHVs. The work includes construction of a 50' native log trail bridge. Construction timber in the form of standing trees will be made available within 5 miles of the bridge site. Equipment cleaning will be required prior to mobilizing to the work site. Refer to the Special Project Specifications for details. The structures listed in the worklogs represent known locations of drainage structures needing work. Additional structures may be located during the project that require maintenance or removal, any work within the scope of the project associated with additional structures or additional required work to AG-0116-S-11-0118 TNF Indian River Road Storage PAGE 5 of36 stabilize the roads located on project roads is considered incidental to the rest of the project work. Many project roads are covered with vegetation such as alder and young spruce growth. The contract also includes an option for additional work furnishing and installing 4"x12" treated wooden planks for the middle joint on 3 modular bridges, and for furnishing and installing 3"x12" untreated wooden planks for the wear surface on the 3 modular bridges. Refer to Sections B and J for optional work details. In-stream timing restrictions are included in the contract for work in streams with fish populations. Refer to Section H for times and locations where this will affect work scheduling. Additionally, a pre- commercial tree thinning contractor will be using road 7500 from the beach to MP 10.935 and road 7502 in its entirety during the spring of 2012. There will be no road storage work allowed on these 2 road segments that interferes with OHV type vehicles before July 1, 2012. The Contractor shall assume all risk, loss, damage, or expense arising out of prosecution of the work, except as otherwise provided in the contract. C.2 Description and Location The project is located on Chichagof Island in southeast Alaska. The Indian River road system is isolated, and is accessible by air or salt water. There are no services available. Tenakee Springs is the nearest community to the work area, however there is no road connection between Tenakee Springs and the work area .. Juneau is the nearest full service community to the work area, approximately 30 air miles towards the east northeast. The Log Transfer Facility (LTF) that serves the Indian River road system is located in Sunny Cove. The present condition of the facility is ringed with a vegetated cover of alder trees. The shot rock fill at the LTF is in place, however the site has not been used for equipment transport since 1999. The Indian River road system is in similar condition, motorized traffic on the roads has been limited to OHVs for approximately 10 years, allowing alder and grass to spread towards the road center. All brush removed for equipment access shall be sidecast below the roadway and shall not be placed in or near streams creating the potential to affect stream flows. C.4 Mobilization Per FP-03, this work consists of moving personnel, equipment, material, and incidentals to the project and performing all work necessary before beginning work at the project site. Mobilization includes the obtaining of permits, insurance and bonds. When 5% of the original contract amount is earned from other bid items, 50% of the mobilization item, or 5% of the original contract amount, whichever is less, will be paid. When 10% of the original contract amount is earned from other bid items, 100% of the mobilization item, or 10% of the original contract amount, whichever is less, will be paid. C.5 Signing and Safety (a) A reflective SLOW MOVING VEHICLE emblem shall be attached to any equipment not designed to maintain a safe travel rate or that will be moving at a slow rate while performing maintenance. (b) It shall be the Contractor's responsibility to furnish black and orange reflective maintenance warning signs to alert motorists of maintenance operations. All signs shall conform to the standards for Temporary Traffic Control in accordance with the Manual of Uniform Traffic Control Devices (MUTCD).

The AEA provided comments on October 31, 2011. AEA comments and Polarconsult responses are summarized below. As appropriate, AEA's comments have been incorporated into the final release of the Indian River Hydroelectric Project Phase II Final Report, dated November 2011. AEA Comments Received (Polarconsult responses in BLUE) 1. Section 2.3 -Refers to "Feasibility Study Report." Please include the title of the report, author, and date so that it is understood exactly which report it is being referred to. Section 2.3 has been modified to state the full name, date and author of the Feasibility Study report. 2. Appendix A: Conceptual Drawings a. Scales don't appear to be correct. In final report, please print on intended page size or fix scales. The conceptual design drawings are formatted as D size drawings (22" by 34"). The printed copies of the Phase II reports include half-size drawings for the readers' convenience. Graphic scale bars are included on all sheets to provide a correct scale regardless of what size paper is used to plot the drawings. This has been clarified in the narrative and on the drawings to avoid confusion. b. Sheet C1.2: The reference roadway section for the road in the steep drop into Indian River canyon (from Sta 16 + 15 to 18 + 40) is listed as Type 2. But the Type 2 section would apply only if the route were sideways to the hill slope, which it is not. A fourth typical roadway section has been added as Detail 6, Sheet Cl.l to represent the main access road from Sta. 16+15 to 18+40, and the callout on Sheet C1.2 has been corrected. 111103-TENAKEEPHASEIIREPORT _APOXE.DOC POLARCONSULT MEMORANDUM c. Sheet C1.2: The 54% grade drop down this steep hill will be a hazard for routine access to the powerhouse after construction. Please comment. The local community is very sensitive to minimizing the roads associated with this project, which is one reason for the proposed powerhouse access configuration. Two means of access to the powerhouse will be available post-construction. For routine personnel access, existing foot trails down this slope are adequate and safe to provide pedestrian access to the powerhouse. For equipment or heavy maintenance access, a permanent winch point will be provided at the top of this grade to allow materials, equipment or vehicles to be winched up and down this grade. Sheet C1.2 has been modified to show these provisions. d. Sheet C3.1: The location of the penstock on trestles in the canyon may be at risk during high water events. The final design for the penstock will evaluate flood stage in the canyon and site the penstock trestle above flood stage to the extent practical. Any penstock trestles that cannot be sited above flood stage will be built to withstand inundation and impact from flood debris (e.g., logs). The penstock design will also evaluate the potential for logs to directly impact the pipe spans and the penstock will be designed accordingly. e. Sheet C3.1-Detail2? Missing profile? Two of the same page? There is not a missing detail. Sheet C3.1 has been corrected. f. Sheet C5.1, Detaill-"leader" /"arrow to" some portions of the drawing are off, i.e., switchgear, load bank. The leaders on Sheet CS.l have been corrected. g. Did not review April drawings 3. The impact of the USFS Indian River Road Storage project upon the access for the Indian River Hydroelectric Project remains a concern to this reviewer. At worst case scenario the removal of existing log bridges and steel culverts by USFS contractors would negatively impact the construction cost of the hydro project. AEA requests the Grantee to continue to communicate with USFS on this issue to reduce these negative impacts as much as possible. The City is maintain an active dialog with the USFS on this issue to work towards an acceptable solution. The USFS has stated that they will make reasonable accommodations for the City's access needs to the project site. The City will keep AEA appraised of the status of these discussions. Page 2 of 2
